<P>PROBLEM TO BE SOLVED: To provide magnetic material which contributes to realizing high performance of a magnetic device. <P>SOLUTION: This method for manufacturing the magnetic material contains a process (a) which prepares composition liquid containing organometallic compound which uses metals showing ferromagnetism as the constituting elements, polyhydric alcohol and at least one kind of anionic surfactant in organic solvent whose boiling point is at least 200°C; a process (b) wherein the mole ratio (A/M), between the ferromagnetic metallic element (M) and the anionic surfactant (A) which are contained in the composition liquid, is set within the limit 3≤A/M<6, the mole ratio (P/M) between the ferromagnetic metallic element (M) and polyhydric alcohol (P) is set to be within the limit of 5<P/M<15, the composition liquid is heated under condition of not oxidizing, and an un-spherical magnetic metal particulate is formed which is a magnetic metal particulate composed of the returned ferromagnetic metallic element and has profile magnetic anisotropy; and a process (c) which collects the magnetic metal particulate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
